Fixes ticket #1058.

* qatar/master:
  h264: Factorize declaration of mb_sizes array.
  vsrc_buffer: when no frame is available, return an error instead of segfaulting.
  configure: add dl to frei0r extralibs.
  dsputil x86: use SSE float instruction instead of SSE2 integer equivalent
  dsputil x86: remove deprecated parameter from scalarproduct_int16 prototype
  vp8dsp x86: perform rounding shift with a single instruction
  fate: add BMP tests.
  swscale: handle complete dimensions for monoblack/white.
  aacenc: Mark deinterleave_input_samples argument as const.
  vf_unsharp: Mark readonly variable as const.
  h264: fix 4:2:2 PCM-macroblocks decoding

Conflicts:

The handler name is stored as a pascal string in the QT specs (first
byte is the length of the string), thus leading to an invalid metadata
string export.

Also add a second length check based on the first character to avoid
overwriting an already specified handler_name (it happens with Youtube
videos for instance, the handler_name get masked), or specifying an
empty string metadata.

To reproduce the problem, using ffprobe:

./ffprobe -show_packets -print_format compact -fflags +genpts -i
fate_samples/mxf/C0023S01.mxf

You will notice that the last video frame does not have it's PTS being
set, even with using genpts.

Allows avoiding the buffer when using avio read, write and seek functions.
When using the ffmpeg executable -avioflags direct can be used to enable
this mode for input files, but has no effect on output files.

pthread_cond_wait is supposed to return an integer,
and indeed does sometimes. Fix its function declaration
to match its behavior and POSIX.

We choose the first encoder by default and libaccplus has a
quite limited set of supported bitrates/sample rates.
Thus leading to failure by default in many cases when it is
enabled at compile time.
Moving it down means that the other aac encoders are favored
by default which avoids this issue.

The reason for this is that such files have IndexTableSegments which when parsed
cover EditUnit ranges like this:

 [0,1)
 [249,250)
 [249,377)
 [0,249)

where each interval is [IndexStartPosition,IndexStartPosition+IndexDuration).
This would be reduced to a sparse index like:

 [0,1), [249,250)

instead of the full range:

 [0,249), [249,377)
